WINDOW-VENTILATOR.

Specification of Letters Patent.

Application filed December 2'7, 1909.

liatented Feb. 114%, 1911.

Serial No. 535,198.

To all whom it may concern:

Be it known that 1, JOHN H. Fnannn, a citizen of the United States,residing at Peoria, in the county of Peoria and State oil Illinois, haveinvented certain new and useful Improvements in i Vindow-Ventilators5and I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to a ventilator par ticnlarly adapted forsleeping rooms although usable elsewhere to advantage.

The object of the invention is to produce a ventilator to be placedbeneath a window that will have certain important advantage over othersof its class.

A t'iiirther object is to improve upon the ventilator forming thesubject matter of my application filed June 16, 1909, Serial No.502,628.

Another object is to produce a ventilator having a pivoted hood with anopen side and a side protected by a screen or perforated wall saidventilator being entirely closed to outside air by means of a door orclosure to exclude such outside air and also to provide a cold storageshelf outside the room and window for edibles.

Other objects will appear as the description of the device proceec Inthe appended drawing -Figure l is a view in perspective of my improvedventilator. Fig. 2 is a vertical transverse section of the same. Fig. 3is a similar view showing a reversed position of its hood. Fig. 4c is anelevation of a portion of the inner or room-surface of the ventilator.Fig. 5 is a transverse section of a portion of the device showing ahinged door or closure.

A indicates a board provided with an opening B to receive a swinginghood C to be described. Said board is intended to lie beneath awindow-sash between the stops of the window frame. It is provided with aslidable extension D held by guides E secured to said board, the latterand the extension D each having secured thereto a spring F to engage thewindow stops and prevent the ventilator rattling. The hood C ispreterably of a length to snugly fit within the opening 13 its end Gbeing quadrant-shaped for convenience and provided with a cylindricallycurved upper wall H, the said ends Gr being pivotally supported withinthe opening B by means of pins J said pins lying at the point from whichthe curve of the wall H is struck so that in the pivotal movement or thehood the curved wall mentioned will always be close to the upper "all ofsaid opening B. The said hood is open at two sides which lie in planesperpendicular to one another and one of them is closed by means or ascreen or perforated wall K the longitudinal edge oi which is secured toa roll or head C formed on the wall H of the hood and its otherlongitudinal edge to a roll extending between the ends G of the hood.lfn one of the positions of the said hood or as shown .in Fig. 2, thescreen h: lies in a horizontal position while in Fig. 2- which shows theopposite position, the screen is substantially perpendicular; the hoodin its movements passing through a quadrant of a circle. A bead U limitsits movement in one direction and a stop C limits the movement in theother direction tl'iough any other means may be employed for thispurpose.

L indicates a closure or door extending tie full length of the hoodbetween its ends G said closure being hinged at its inner edge to thewall H of the hood at the inner edge of the screen I: and it of such awidth as to entirely cover the screen. Upon the inner sideof one of thealls G is secured a spring N upon which the door L is adapted to rubwhereby said door maybe adjusted to any desired position and held byfriction.

in the board A. Fig. 4;, is .a socket A to receive a spring A and aplunger A the latter through said spring adapted to i'rictionally engagethe adjacent end G oi the hood and serve to hold that member in anydesired adjustment.

An advantage of my type or": ventilator is that the hood may be adjustedto any position within the room so as to direct the air currentsdownward to the floor particularly if the window is near a bed and thispurpose is also the design of my former application referred to but moreparticularly in the present instance I am enabled to regulate theamountot air entering the room by adjusting the door or closure L sothat little or much air can be admitted the spring N serving to hold thedoor in any desired po sition regardless 01" strong winds that may beblowing. A further advantage is that the screen K is carried by and ismovable with the hood and in one of its positions lies horizontallyoutside the room whereon articles of food may be placed to keep themfresh and cool while being protected from dust and rain by the hood andin freezing weather the door L may be closed and the articles placedupon it, with little danger of freezin An important point is that byhaving the screen atlixed to and movable with the hood there is no spaceleft through which insects can crawl as would result perhaps if the hoodmoved relative to said screen especially if the space between the latterand the hood is increased in case the hood is damaged. Drafts arisingthrough the screen K in the ventilator will of course be directedhorizontally into the room. In order to direct the current downward thehood may be positioned for instance as shown in Fig. 3 or in someintermediate position so that the currents on entering through thescreen can be sent directly downward, or downward at an. angle to thefloor and the door or closure may be adjusted to assist in this sinceits hinge, see in the figure mentioned, is at the top of the hood. Theair after impinging upon said closure is deflected in a downwarddirection and in any quantity depending upon the extent of the opening.

As distinguished from the prior art the door or closure L while closingthe passage through the hood to the entrance of air, forms a shelf inthe same way as does the screen K so that either may be used as thecondition of the weather may require. In either way the device is ofconsiderable utility.

The devices of which I am aware are not constructed so as to have theadvantages described since although a closure is used in one of theventilators of the art it must be placed in a vertical position in orderto close the hood to the passage of air and thus has no other utilitythan as a closure.

I am aware of another device that has a screen that can be placed in ahorizontal position but when the device is moved on its supporting axisto close it to the passage of air the screen is placed beyond reach andcannot be used as a shelf. My device, then, differs from those mentionedin that it presents a shelf for use whether the air is excluded or not.It difiers also in that while being tiltable in order to direct thedrafts downward into the room its closure can be adjusted to admit moreor less ai' as desired.

Having thus described my invention, I claim 1. In a ventilator of theclass described, a support, a hood pivoted at its lower side to andadapted to swing outward beyond either side of said support and havingan upper protecting top side and open through two of its other sides, aperforated member secured in the hood in one of its open sides, and aclosure for said hood hinged to and carried by it adjacent to theperforated member and adapted to lie substantially parallel to saidmember.

2. In a ventilator of the class described the combination of a memberhaving an opening therethrough, a hood having closed end por tionspivoted at their lower ends to said member within and near the bottom ofthe opening and'having an upper cylindrically curved side and open attwo other sides, a perforated member secured to the hood in one of itsopen sides, and a closure pivoted within the latter adjacent saidperforated member and arranged to cover the same.

3. In a ventilator of the class described, the combination of a memberof two parts adjustable in length having an opening tl'ierethrough, ahood having closed end portions pivoted at their lower ends to saidmember within and near the bottom of the opening and having an uppercylindrically curved side and open at two other sides, a perforatedmember secured to the hood in one of its open sides, and a closurepivoted within the latter adjacent said perforated member and arrangedto cover the same.

4:. A ventilator consisting of a member provided with an opening andadapted to be placed beneath a window sash, a hood having a positionwithin the said opening consisting of quadrant shaped end portionspivoted at their apices to the end walls of the openings at its bottomand adapted to move through said opening and having a cylindricallycurved top wall substantially concentric with the pivots of said ends,said hood having a passage through it, a perforated partition fixed inposition within the hood at one extremity of the passage, and a closureadapted to overlie the partition and hinged in the top of the hoodadjacent to the said partition.

In testimony whereof I aflix my signature, in presence of two witnesses.

JOHN H. FRANKIE.
